Explain about Chromosomes . Provide a pic

Answer 1

THE THREAD-LIKE STRUCTURES PRESENT IN THE NUCLEUS OF A CELL ARE CALLED CHROMOSOMES. THESE CARRY GENES WHICH HELP IN THE TRANSFER OF CHARACTERS FROM THE PARENT TO THE OFFSPRING.

Chromosomes are the structures which contain DNA. The DNA in turn contains genes. Chromosomes are the hereditary structures which are inherited from generation to generation. To you these chromosomes came from your father and mother(half from your mother and half from your father). Half the chromosomes which came from your father carried the characters of your father and half the chromosomes which came from your mother carried the characters of your mother. These chromosomes carry all necessary information to carry out different functions of the cell or insense it is the genes in the chromosomes which guide the cell in performing different functions like

1. Guiding the cell in cell division

2. Plays an important role in inheritance of characters from generation to generation.

3. Guiding protein synthesis.

4. Performing carbohydrate, protein and lipid metabolism.

5. Self repairing.


If chromosomes are absent, the cell can not perform different function as it doesn't know how to do them. So a chromosome has information for all the functions to be carried out by the cell.

Answer 2

there are 24 sets of chromosomes. they have our DNA . they carry out our jeans.xx leads to female chromosomes and XY chromosomes lead to male chromosomes. if xx chromosomes of female meet with the XY chromosomes of the male, a zygote is formed.
